TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No, 468,199, dated February 2, 1892.

Application filed November 3, 1891. Serial No. 410,736. (No model.)

T all whom, it may concern:

Be it known that I, ADoLPH A. HUNZIKER, of St. Louis, Missouri, have invented a new and Improved rTemporary Binder, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which` Figure l is a perspective view of my improved temporary b'inder. Fig. 2 is a longitudinal section of the binding device, taken online 2 2 in Fig. (i. Fig. 3 is a longitudinal section. Fig. 4E is a transverse section of a modified form. Fig. 5 is a longitudinal section of the same, and Fig. 6.is a transverse section taken on li-ney G 6 in Fig. 2.

Similar letters of reference indicate corresponding parts in all the views.

The object of my inventionA is to construct a simple and efficient binder for temporarily binding magazines, loose pamphlets, blank books, &c.

My invention consists in a back-support, one or more fixed hooks adapted to enter between the leaves of the pamphlet, one or more spring-actuated sliding hooks, and a cover, all as will be hereinafter more fully described.

The back of the binder consi-sts of a plate A, of metal or other suitable material, having its edges bent over toward the center thereof to receive the edges of the convex plate A', which forms a cover to the working parts and gives suitable form to the back of the binder. To one end of the plate A is attached a double hook a, formed of a right-angled loop of Wire bent over and returned parallel with itself i with its free ends pointed.' The said double hook passes through perforations in the an gled end of the plate A. To the back of the plate, near the opposite end,is secured a strip h, which is bent into loops c, forming, together with the perforated angled end of the plate A, guides for the sliding hook B, the said sliding hook being made of a wire bent into the form of a rectangular loop, and then bent or returned parallel with itself, so that the outer ends of the sliding hook extend over t-he face of the plate A and parallel therewith. For convenience in handling, a loop d is attached to the arms of the hook B. The extremities of the Wire forming the hooks are pointed, so that they will readily enter between the leaves of a book or pamphlet. One end of a spiral spring C is attached to the hook B, and the other end of the spring is attached to a stud e, projecting from the back of the plate A.

The plate A, with its cover A', is inserted 1n the back of the cover D and held in place by a strip f of leather, and the spring and movable parts vof the binder are covered by the back portion of the cover.

By drawing out the double hook B and placing the magazine or pamphlet on the double hook a, allowing the pointed ends of the said hook to enter between the leaves of the pamphlet and then allowing the pointed ends of the double hook B to enter between the leaves of the pamphlet, the pamphlet is secured in place in the binder.

lVhere it is desired to attach my improvement to a memorandum-book or a single pamphlet, the back of the cover is provided with a tube A2, in one end of which is secured the hook a', formed of a piece of wire bent twice at right angles with the ends parallel, the outer ends being pointed, as shown. In the other end of lthe tube is inserted a wire b2, provided with a head c on its inner end. A spiral spring cl surrounds the wire h2 and presses in one direction against the head c', and in the other direction against a fillet e in the end of the tube. The wire b2 outside of the tube A2 is curved to form a loop f and its extremity is bent parallel with the tube A2. The tube A2 is held in place in the cover g by the leather strip h. By drawing out the wire b2 against the'pressure of the spring d and inserting the pamphlet or book, as shown in Fig. 5, with the pointed end of the hook a between the leaves, and allowing the pointed end of the wire h2 'to enter between the leaves, as shown, the book is fastened in the cover.

Having thus described my invention, I claim as new and desire-to secure by Letters Patentl. In a temporary binder, the combination, with a support provided with one or more pointed hooks adapted to enter between the leaves of a book at one end, of one or more sliding spring-actuated hooks adapted to euter between the leaves at the opposite end, substantially as specified.

2. In a temporary binder, the combination IOO of the plate A, the sliding hook 3, the spring,` C, drawing the hook inward, the fixed hook ce, projecting toward hook B, and the cover D, substantially as specified.

3. In a binder, the Combination ol' the plate A, provided with one o1' more pointed hooks a, the sliding hooks B, the spring C, the transverse strip secured to the hack of plato A and
